With real ontological wave functions the Einstein Podolsky Rosen paradox
means instantaneous action over a large distance. Contrary to lore
it does not violate the essence of special relativity which just prescribes
boost transformations (Our hope is that following't Hooft [1]} that general
relativity can be formulated in a unitary way even around singular
structures like black holes and that following Donoghue [2]}
in absense of of quantum jumps quantum field theory can be implemented
in general relativity involving integrals over products of fields. That coexisting paths may lead to different final gravitational field
configurations presents no problem for the argument given below). However, using relativity instantaneous action means backward causation
in a different Lorentz system [3]} which is widely
considered unacceptable.
